This should work.
AFAIK you need Adobe Reader 5.0 for this feature, so you have to set the PDF level in PDFsharp to 14.
Code:
        PdfDocument document = new PdfDocument(filename);
        document.Version = 14;


It works for some PNG files with transparency. If you have a PNG file that is not supported, please mail us a sample so we can add that format to PDFsharp.

See XGraphicsLab for some working examples.
